Synthesis of α-amino phosphonic acids via oxoiminium salts

The oxoiminium salts 4a, b, and 8 obtained by alkylation with Et3OBF4 of the aldonitrones 3a, b, and 7 react with diphenyl hydrogen phosphite to give the N‐alkoxy α‐amino phosphonic esters 6 and 9a, b. Similarly, the cyclic imine oxides 10a, b and the cyclic oxime ethers 14a, b afford the α‐branched...
